I don't train hard my feet after LL because I feel them weaker than before and I have some balance issues due to atl I did.
After my right tibia straightening and at shortening 5 months ago I am much more stable but I still don't train hard my legs as I am still in rehabilitation stadium.
I think that someone can build a good amount of muscles on feet even after LL.
Personally I never wanted too bulky feet as they make me feel shorter and I have problems in finding trousers so I am not the most suitable person to ask.
If you want to talk about arms, here I am.
